   I just picked up an HP DeskJet 500 inkjet printer and connected it to
my Apple ][GS. I've had a few difficulties with it, and I was wondering
if there's anything else I can do to fix things. I don't have an Epson
emulation cartridge.
   I can't do the old "PR#1" then "TYPE <filename>"  from BASIC or
"type <filename> > .printer" from ORCA. The printer port firmware ORAs
in the high bit, which selects graphic characters in the printer, and
doesn't invoke carriage returns. I always get a single line of greek
characters, mathematical symbols, and line art. The printer never sees a
command to begin a new line. Note that AppleWorks and similar programs
do not have this problem, as they (apparently) don't go through the
$C107 entry point with the offending ORA #$80.
   This is the thing I most want help with. I really miss being able to
print from BASIC programs or printing out ORCA program listings.
   Second problem is that DeluxePaint ][ draws 6 horizontal lines across
each page printed under the Vitesse Harmonie printer drivers. These
lines are always across the short width of the page, whether the picture
is being printed in portrait or in landscape mode. This does not happen
with BeagleWrite when it prints in non-draft mode.

   Setup:
Apple ][GS with 4MB RAM
Apple DMA SCSI and 45MB cartridge removeable drive
Applied Engineering DataLink 2400
Zip GSX

Printer port:
8N1, 19200bd, no DCD, no XON/XOFF, DTR on, line length unlimited, no echo,
add line feed after CR, buffering on

Printer DIP switches:
Character set PC-8, Paper size US letter, CR defn CR only, perforation
skip enabled, text scale mode 63 lines/page, graphics density 75 DPI,
terminal mode enabled, RS-232-C baud rate 19200, RS-232-C parity 8 bits
no parity, handshaking DTR.
